FALSE LAYER SYNDROME IN A COMMERCIAL LAYER FLOCK ASSOCIATED WITH INFECTIOUS BRONCHITIS VIRUS VARIANT

| description | False Layer Syndrome is a permanent condition that prevents hens from laying eggs as a
consequence of early infectious bronchitis (IB) virus infection. Cystic oviduct associated with the reduced
peak of egg production in apparently healthy layer flock was diagnosed. Considering the flock history
different viral and bacteriological tests were done. Any evidence of bacterial infection was not found. IB
virus (IBV) was detected in caecal tonsil samples, suggesting early IB virus infection, an isolated virus
phylogenetically belonging to the Variant 2 genotype. However, it is the first report of a Variant 2
genotype causing cystic oviducts in Iran, complementary studies are needed to investigate the pathogenicity
of these viruses for oviduct and their ability to develop cystic oviducts.
